after upgrading to macOS Monterey 12.0.1
Video Conference Tool: FaceTime, Google Chrome, Zoom
No video stream was available when you connect with USB
Tried all different ports, cables , VCA
No change in settings and permission
Camera has been working fine prior to MAC OS update
Have been pulling my hair out with this. The support team for my webcam hinted that some people are having success with different cables. I bought new cables and tested lots of combinations. The only thing that works is using USB-FI certified USB 3.1 gen1 or USB 3.0 gen1 cables.
Even the dell 3.1 gen2 cable that came with my USB-C monitor only worked at usb 2.0 speeds, but replaced with a gen1 cable and it is connecting at 5gbps.
Now my display, dock and all devices are connecting properly.

Have the required accesses been given in Security & Privacy?
The issue isn't with the camera. Many people are experiencing similar problems with USB ports
Yes for camera and apps necessary access are given
Not yet resolved
I encountered the logitech usb failure after upgrading to Monterey.
And now it's back to 480mbps. Didn't change anything, just plugged it back in this morning. ****

It appears that some cameras are just not compatible with Monterey. I would go to Support site for your specific camera
